GEORGE F. SIMONDS, OF FITOHBURG, MASSACHUSETTS.

ARMOR-PIERCING SHELL.

SPECIFICATION forming part of Letters Patent No. 348,789, dated September 7, 1886.

Application filed April 8, 1886, Serial No. 198,253. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE F. SIMONDS, of Fitchburg, in the county of \Vorccster and State of Massachusetts, have invented a new and Improved Armor-Piercing Projectile or Shell; and I hereby delare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figurel is a perspective view of an ingot made in any desired way, from which my improved projectile is to be made, the opening in the ingot being shown in dotted lines. Fig. 2 is alongitudinal sectional view, in perspective of the same. Fig. 3 is a side elevation of the projectile as it appears on the completion of the rolling from the ingot and still attached to the stub or waste of the ingot. Fig. 4is a longitudinal sectional view of a completed projectile, and Fig. 5 shows a modification of the same.

My invention has particularly for its object the formation of an armor-puncturing shell or projectile; and it consists ina projects ile wherein the walls are thickened and reinforced in a very great ratio at the point, whereby I am enabled to utilize the forward end of the shot as a puncturing portion to make an opening for the passage of the body or weaker portion containing the burstingcharge.

My invention further consists in rolling such a shell from aningot cast or otherwise formed partially hollow, whereby I am enabled to make the projectile in one homogeneous mass of metal.

In order'that those skilled in the art may make and use my invention, I will proceed to describe the manner in which I have carried it out.

In thesaid drawings, a is a blank or ingot cast, forged, or otherwise produced with a solid portion, 1), and a hollow portion, (1. The ingot thus formed is heated and treated under the method, and with the apparatus and properly-formed dies described and claimed in my application for patent filed March 24,1885, Serial No. 160,016, whereby the ingot is shaped, compacted, and pointed as shown in Fig. 3, and the base drawn together to form the opening through which to insert the burst ing-charge.

It will be seen that in the operation of forming the armor-puncturing shell the point of the shell is substantiallya solid body, 0, of condensed compacted metal with the skin on it, and forming thereby the most desirable and effective character of puncturing-projectile.

In the modification shown in Fig. 5 the base of the shell is fitted for the insertion of a screw-plug, if it be desirable to use one.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. Ahollow projectile rolled to form, and the metal condensed and hardened all at one operation, provided with the solid puncturing portion 0, as set forth.

2. The method of making hollow projectiles herein described, consisting, essentially, in preparing a cylindrical ingot hollow a portion of its length, and then rolling said ingot so as to form the solid portion into the forward end of the projectile while the hollow portion is formed to properly hold a burstingcharge, as specified.
